Company Identifies Significant Cesium Enrichment in CV5 and CV13 Pegmatites

Following the transition of the CV5 Pegmatite models to the Feasibility Study team, the Company has conducted a thorough review of its core assay dataset. This process led to the identification of multiple distinct areas with significant cesium (Cs) enrichment, specifically with levels exceeding 1% Cs₂O. These regions include the CV5 and CV12 pegmatites, although the most substantial findings are associated with the CV13 Pegmatite.

Recent Drill Results Highlighting Cesium

The latest drilling and channel assay results (Figure 1, Table 1, and Table 2) reveal impressive cesium concentrations:

• 10.4 m at 1.30% Cs₂O, including 4.0 m at 2.02% Cs₂O (CV23-117) at CV5.
• 10.6 m at >1.00% Cs₂O (CV24-754) at CV13 – Cs overlimits pending.
• 7.1 m at >1.00% Cs₂O (CV24-520) at CV13 – Cs overlimits pending.
• 0.5 m at 9.58% Cs₂O (Channel CH22-047) – CV12.

Currently, overlimits for cesium concentration (>1% Cs₂O) are pending for over 140 core samples from the 2024 summer-fall drill program, with roughly 100 of these samples from the CV13 Pegmatite. These overlimits are necessary when analytical results surpass the upper detection limit, which, in this case, is >10,000 ppm Cs (equating to 1% Cs). Final calculations for cesium grade-width in drilling holes, including CV24-520 and CV24-754, will be available once overlimit analyses are completed.

Characterization of Cesium Zones at CV13

Two prominent areas of cesium enrichment have been identified at CV13 (Figure 1). The first and most significant zone overlaps with the high-grade lithium zone known as the Vega Zone. This zone extends over a substantial area of approximately 600 m x 400 m, with thickness varying from 1-2 m to as much as 10 m (core length). The second zone correlates with the apex of structural flexure at CV13, estimated to cover an area of around ~250 m x 50 m and several meters thick.

Pollucite, the primary ore mineral for cesium, has been confirmed through XRD mineralogical analysis at Shaakichiuwaanaan, suggesting it as the source of the observed cesium enrichment at the property. A targeted mineralogical program focusing on cesium-rich areas is currently underway.

Moving forward, the Company aims to utilize its drill and surface sampling data to refine the geological model of cesium enrichment within the larger pegmatite body across primary occurrences, particularly around the Vega Zone area of CV13. Plans are in place to incorporate cesium into the block model to assess these occurrences further.

The discovery of significant pollucite mineralization at CV13 opens avenues for exploring cesium as a potential by-product. This prospect could complement the Company’s ongoing lithium-focused development strategy. As the Feasibility Study for CV5 progresses, the Company intends to evaluate the cesium resource potential at Shaakichiuwaanaan and consider its implications for future exploration and development.

Understanding Cesium: A Rare and Critical Metal

Cesium (Cs) is a specialty metal, recognized as a critical and strategic mineral by Canada, the province of Quebec, Japan, and the United States. Primarily extracted from the mineral pollucite, cesium is utilized mainly in the form of cesium formate brine due to its high density, low toxicity, and biodegradable nature. This brine plays a crucial role in facilitating the completion of oil and gas wells under high-pressure and high-temperature conditions.

Exploring Cesium’s Unique Role and the Shaakichiuwaanaan Property

Cesium is integral to various high-tech applications, including atomic clocks, GPS, aircraft navigation, and telecommunications. Its compounds serve important functions across industries: cesium carbonate is used in fuel cells, cesium chloride in chemistry and nuclear medicine, cesium hydroxide powers batteries, and cesium iodide is essential in X-ray equipment. Additionally, cesium nitrate finds application in pyrotechnics and scintillation counters, while cesium sulfates are utilized in water treatment and scientific instruments.

Rarity of Cesium Mineral Deposits

Mineral deposits of cesium, specifically pollucite, are exceptionally rare, representing a highly fractionated component of lithium-cesium-tantalum (LCT) pegmatites. These pegmatites are virtually the sole primary source of cesium worldwide. Economic deposits generally range from <10 kilotonnes (kt) to 350,000 kt, in stark contrast to lithium pegmatite deposits, which often exceed millions of tonnes, typically falling between <10 million tonnes (Mt) and rarely surpassing 100 Mt. Current and historical cesium-producing mines include Tanco in Canada, Bikita in Zimbabwe, and Sinclair in Australia. Notably, Sinclair, Australia’s first commercial cesium mine, ceased production in 2019.

Quality Assurance and Control in Exploration

Quality Assurance / Quality Control (QAQC)

To ensure the accuracy and reliability of exploration results, a Quality Assurance / Quality Control protocol was implemented according to industry best practices. This protocol included the systematic insertion of quartz blanks and certified reference materials into sample batches at a rate of approximately 5% for each. Additionally, duplicates of pulp-split samples were analyzed to verify analytical precision, and external laboratory pulp-split duplicates were prepared for further validation.

All collected samples were sent to SGS Canada’s laboratories in Val-d’Or, QC or Radisson, QC for initial preparation (PRP90 special), which includes drying, crushing, riffle splitting, and pulverizing to achieve specified particle sizes. The resulting pulps were then air shipped to SGS Canada’s facility in Burnaby, BC for homogenization and subsequent analysis of multi-elements, including lithium (Li), cesium (Cs), and tantalum (Ta) through sodium peroxide fusion combined with ICP-AES/MS techniques.

When analytical results for cesium exceed the upper limit of 10,000 ppm, overlimit packages utilizing acid digestion processes are requested to report cesium concentrations as a percentage.

# Comprehensive Review of Sampling Techniques for Mineralization Studies

## Sampling Appropriateness and Methodology

In mineral exploration, employing suitable sampling methods is crucial to represent the type and characteristics of mineralization accurately. This careful approach ensures that the samples provide a reliable reflection of the surrounding geological environment.

## Verification of Sampling and Assaying Procedures

To maintain high data integrity, it’s essential to have stringent verification processes for both sampling and assaying. Several methods are applied, including:

• Independent verification of significant intersections by either external auditors or company personnel.
• Utilizing twinned drill holes to validate results.
• Thorough documentation of primary data, including data entry methods, verification processes, and storage protocols for both physical and electronic data.
• A discussion of any necessary adjustments to assay data.

In addition, the overall review and compilation of intervals are conducted by the VP of Exploration and Project Managers before any public disclosure, incorporating checks against the company’s internal QAQC sample analytical data.

Various QAQC protocols are enacted on-site and afterwards to preserve data integrity and accuracy.

Any adjustments to the reported assay data include the conversion of lithium, tantalum, and cesium into their oxide forms, utilizing standard formulas such as Li₂O = Li x 2.153, Ta₂O₅ = Ta x 1.221, and Cs₂O = Cs x 1.0602.

## Location of Data Points

The accuracy and quality of location surveys are pivotal in determining the positioning of drill holes, trenches, and mines necessary for Mineral Resource estimates. Key considerations include:

• Accuracy of surveys for collar locations and down-hole readings.
• Specification of the grid system utilized in these surveys.
• Quality and adequacy of topographic controls that affect project outcomes.

For precise positioning, each drill hole has been surveyed using either an RTK Trimble Zephyr 3 or Topcon GR-5 systems, with a limited number of surveys done via handheld GPS devices. The coordinate system for the surveys is based on UTM NAD83 Zone 18. A comprehensive property-wide LiDAR and orthophoto survey was conducted in August 2022, which has fortified the topographic control necessary for advanced exploration and the estimation of resources.

## Data Spacing and Distribution Insights

The arrangement and distribution of data directly impact the mineral exploration results. Important factors include:

• The spacing of data in relation to Exploration Results.
• The adequacy of data distribution to meet the parameters required for geological and grade continuity necessary for Mineral Resource and Ore Reserve estimations.
• Application of sample compositing in data analysis.

Overall, this meticulous attention to sampling methods, data verification, and spatial analysis provides a strong foundation for accurate mineral resource assessment and strategic planning.

Overview of Drill Hole Spacing and Sample Security Procedures

This analysis discusses the drill hole spacing techniques across various sites, sample security measures, and audit reviews related to the mineral exploration activities being conducted.

Drill Hole Spacing Patterns

• Drilling at CV13 predominantly follows a grid pattern, targeting pegmatite pierce points approximately every 100 meters. However, collar locations and orientations may differ significantly, influenced by the pegmatite body’s varying orientation along strike.
• At the CV9 site, drill hole collar spacing is irregular, with different hole orientations and multiple collars present on the same pad.
• The interpretation shows that most drill hole spacing at each site is adequate to support a mineral resource estimate.
• Core sample lengths typically range from 0.5 to 2.0 meters, with an average length between 1.0 and 1.5 meters. Continuous sampling occurs within all encountered pegmatite during drilling.

Orientation of Data Related to Geological Structures

Understanding the orientation of sampling in relation to geological structures is crucial for obtaining unbiased results. Three critical points arise from this assessment:

• The drilling orientation must accurately reflect possible structures and the extent of understanding concerning the deposit type.
• If a sampling bias is introduced through the drilling orientation versus mineralized structures, this should be assessed and reported if significant.
• It is anticipated that no sampling bias will occur based on the structure within the mineralized body. The main mineralized bodies remain relatively undeformed and competent, yet exhibit some structural control.

Characteristics of Pegmatite Bodies

• At CV5, the primary mineralized body and adjacent lenses are steeply dipping, meaning intersections can vary in true widths depending on drill hole angles and pegmatite orientations. Observations demonstrate that true widths may not be clear until several holes are drilled in an appropriate pattern.
• CV13 hosts a principal pegmatite body characterized by a shallow and varied strike and a northern dip.
• At CV9, the pegmatite’s orientation and geometry are not clearly defined. It is interpreted as a single principal dyke, outcropping at the surface with a steep northerly dip and moderate plunge to the east-southeast.

Sample Security Measures

Assured sample security is fundamental throughout the drilling process. The measures include:

• Samples are collected by company personnel or consultants following strict sample collection and handling protocols. Each core sample is bagged, placed in large supersacs for security, palletized, and shipped directly to laboratories in Val-d’Or or Radisson, QC. Chain of custody principles are followed during shipments.
• Upon reaching the laboratory, samples are cross-referenced with the shipping manifest to confirm the complete and accurate receipt of samples. Laboratory staff also evaluate sample bags for signs of tampering.

Audits and Reviews of Sampling Techniques

Regular audits help ensure the integrity of sampling methods. A summary of recent evaluations includes:

• A review of the sample procedures from the company’s 2021 fall drill program (CF21-001 to 004) and the 2022 winter drill program (CV22-015 to 034) was conducted by an Independent Competent Person. This review confirmed that the procedures align with industry best practices.
• Further assessment of sampling procedures continues as part of the ongoing commitment to maintain high standards in exploration activities.

This comprehensive approach ensures robust data collection and sample integrity as exploration activities continue across various sites. Through careful monitoring and evaluation, the company aims to uphold its reputation in mineral exploration while adhering to industry standards.

Geological Overview and Drill Information for Lac Guyer Greenstone Belt

Geology	Deposit type, geological setting, and style of mineralization.	The Property lies over a significant portion of the Lac Guyer Greenstone Belt, which is part of the larger La Grande River Greenstone Belt. This area is characterized by volcanic rocks metamorphosed to the amphibolite facies. The claim block predominantly consists of the Guyer Group’s rocks, including amphibolite, iron formation, intermediate to mafic volcanics, peridotite, pyroxenite, and komatiite, along with felsic volcanics. These amphibolite rocks trend east-west and dip steeply to the south, bordered to the north by the Magin Formation (conglomerate and wacke) and to the south by an assemblage of tonalite, granodiorite, and diorite, alongside Marbot Group metasediments (conglomerate, wacke). Additionally, several regional-scale Proterozoic gabbroic dykes traverse the Property. The geological setting presents a promising potential for gold, silver, base metals, platinum group elements, and lithium across various deposit styles. This includes orogenic gold (Au), volcanogenic massive sulfide (Cu, Au, Ag), komatiite-ultramafic (Au, Ag, PGE, Ni, Cu, Co), and pegmatite (Li, Ta). Exploration has delineated three main mineral exploration trends: the Golden Trend (gold), Maven Trend (copper, gold, silver), and CV Trend (lithium, tantalum). The CV5 and CV13 spodumene pegmatites are located within the CV Trend. Lithium mineralization is noted at the Property, especially at CV5, CV13, and CV9, occurring within quartz-feldspar pegmatite, which often appears as high relief ‘whale-back’ landforms. The pegmatite shows a coarse-grained texture, typically off-white, with darker sections containing mica, smoky quartz, and occasional tourmaline. The lithium pegmatites at Shaakichiuwaanaan are classified as LCT Pegmatites. Ongoing assays and mineralogical studies confirm that spodumene is the prevalent lithium-bearing mineral, devoid of significant petalite, lepidolite, lithium-phosphate minerals, or apatite. The spodumene crystals are generally decimetre-sized, indicating substantial size. Moreover, the pegmatites possess notable tantalum values, with tantalite identified as the indicative mineral phase.
Drill Hole Information	A summary includes crucial information relevant to understanding the exploration results, specifically a tabulation of the following details for all significant drill holes: easting and northing of the drill hole collar elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar dip and azimuth of the hole down hole length and interception depth hole length. If the exclusion of certain information is justifiable due to its insignificance and does not hinder report understanding, the Competent Person should clarify the reasons for such exclusions.	Drill hole attribute information is contained in a table included herein. Intersections of pegmatite less than 2 m are generally not reported, as they are deemed insignificant.
Data Aggregation Methods	In reporting Exploration Results, standard practices include employing weighting averaging techniques, defining maximum and minimum grade truncations (e.g., cutting high grades), and identifying cut-off grades, which are generally considered material and should be detailed. When aggregate intercepts comprise short high-grade results alongside longer low-grade results, the method used for classifying these intercepts should be clearly stated.

“`# Key Reporting Guidelines for Mineral Exploration Results

## Clarity in Reporting Metal Equivalent Values
When reporting metal equivalent values in mineral exploration, it’s crucial to clearly state the assumptions used behind the calculations. This approach ensures that stakeholders understand the methodology and contextual factors impacting the reporting.

### Examples of Aggregation
– **Grade Over Width Calculation:** In this process, length-weighted averages were utilized to determine the grade across various widths.
– **No Cut-offs Used:** Notably, during these calculations, no specific grade cap or cut-off was applied. For the lithium and tantalum grades, the length-weighted average grade was computed for all pegmatite intervals exceeding 2 meters in core length. Additionally, higher-grade zones were included at the discretion of the geologist.
– **Dilution Considerations:** Pegmatites naturally exhibit inconsistent mineralization. Therefore, any dilution from non-pegmatite material is typically constrained to less than 3 meters where applicable and marked accordingly in assay reports.
– **Metal Equivalents:** It is worth mentioning that no metal equivalents were reported for this analysis.

## Understanding Mineralization and Intercept Lengths
The relationship between mineralization widths and intercept lengths plays a vital role in effectively summarizing exploration results.

### Caveats in Reporting
If the geometry of mineralization relative to the drill hole angle is known, it should be disclosed. However, should the geometry be unknown and only downhole lengths are reported, a clear statement indicating the uncertainty is essential. For example, note that “downhole length, true width not known.”

### CV Pegmatite Insights
At CV5, ongoing geological modeling continues as assay results are received. Current interpretations suggest a primary large pegmatite body with a near vertical to steep dip, surrounded by several smaller pegmatite lenses, collectively referred to as the **CV5 Spodumene Pegmatite**.

At CV13, a similar process of geological modeling is underway, with emerging interpretations indicating a series of sub-parallel trending sills demonstrating a flat to shallow dip toward the north, together identified as the **CV13 Spodumene Pegmatite**.

At CV9, preliminary interpretations suggest a singular principal dyke, which is visible at the surface and has a steep northerly dip, moderately plunging to the east-southeast, with a delineated strike length of 450 meters confirmed through drilling and outcrop examination.

It’s important to note that all reported widths represent core length, and true widths have not been calculated at this stage due to wide drill spacing, typical irregular nature of pegmatites, and varied drill hole angles. As a result, true widths may differ significantly between holes.

## Inclusion of Diagrams
Appropriate maps and sections, complete with scales, are critical in reporting any significant discoveries. These should include a comprehensive plan view of drill hole collar locations and relevant sectional views.

For actual diagrams and figures, please refer to those included in the report and published on the company’s website.

## Commitment to Balanced Reporting
In circumstances where comprehensive reporting of all Exploration Results isn’t feasible, it is essential to practice representative reporting of both low and high grades and/or widths. This avoids misleading interpretations of the exploration results.

For additional details, please consult the tables provided within this report, as well as in the company’s online resources.# Patriot Battery Metals Progresses with Exploration on Shaakichiuwaanaan Property

Patriot Battery Metals Inc. is advancing exploration on its Shaakichiuwaanaan Property, focusing on the CV5 and CV13 pegmatite areas. The company is currently completing essential site environmental assessments. Alongside these activities, a bathymetric survey has been finalized over the glacial lake that partially covers the CV5 Spodumene Pegmatite. This lake’s depth varies, with much of the pegmatite being overlain by less than 2 to 10 meters of water.

## Significant Metallurgical Testing Results

Recent metallurgical tests show promising results. The tests, which included Heavy Liquid Separation (HLS) and magnetic testing, produced spodumene concentrates of over 6% Li₂O with recovery rates exceeding 70% from both the CV5 and CV13 pegmatite materials. Notably, a DMS (Dense Media Separation) test on the CV5 material yielded a spodumene concentrate with 5.8% Li₂O at a recovery rate of 79%. These findings strongly suggest the viability of a DMS-only operation for both sites. Furthermore, an extended DMS pilot program conducted with non-pegmatite dilution aligns with previous findings.

## Ongoing Feasibility Studies

The company has initiated various mandates essential for advancing the project toward feasibility. These include studies on environmental baseline conditions, metallurgy, geomechanics, hydrogeology, hydrology, stakeholder engagement, geochemical characterization, and evaluations of mining logistics and transportation.

## Plans for Further Exploration

Looking ahead, Patriot Battery Metals is planning additional exploratory work. This includes tests for lateral and depth extensions and large-scale step-out drilling. The company also intends to continue drilling efforts, focusing on the pegmatites of the Shaakichiuwaanaan Property, particularly the CV5 Pegmatite and its surrounding subordinate lenses, along with the CV13 Pegmatite and associated prospective corridors.
